Feeling lonely can make you sick. Doctors have long known that loneliness can cause many health problems and even death. What they didn’t know is   16  this feeling causes illness. A study in the online magazine Genome Biology  17  that loneliness actually influences the important part of our bodies—our genes.
In a small population of patients, researchers   18  more than 20,000 genes to compare how the genes of lonely and non-lonely individuals (个体) express themselves in molecular processes (分子过程) and in personal health. They found that gene expression is   19  in chronically (长期地) lonely people. “We now have a new way for understanding the relationship   20   social experience and physical health,” explains the study’s lead author, Steve Cole of University of California, Los Angeles.
“This study—the first to link (联系)   21  with gene changes—is special and exciting,” says Emma Adam, a professor of human development at Northwestern University. “It   22  in the black box.”
According to John Cacioppo, an author of the study from the University of Chicago, the
work suggests that loneliness is a warning   23 , much like physical pain. “This feeling is so bad because   24  of us wants to be forgotten; that’ s also what human means,” he says. “It makes us   25  for other people and want to be with friends when we’re lonely.”

Eighth-grader Victoria Bills is talking about money with her classmates. She is worried that a company’s stock (股票) price could fall. It may be an unusual topic of conversation for a 13-year-old. But at Bills’ school in Chicago, US, you hear it all the time.
The Chicago school’s 420 students learn about economic(经济学). They also get a chance to make money. Each 1^st grade and 5^th grade, students learn the basics of economics and investing(投资).
Then in 6^th grade, they put what they’ve learned to work. Students join a junior group that manages the $20,000. The group, made up of 12 to 14 students, decides which stocks to buy.
After graduating, students pass on $20,000 to the next 1^st grade class. They keep half of the rest of the money; the other half goes toward improving the school. They can choose to put their money in a college-savings program or take the cash.
In 2007, Bills suggested that her class buy the stock of the Apple computer company. This was just before the iPhone came out. “We bought stock just at the right time,” she says. The kids bought Google stock as it reached $400 a share. It is now worth over $500. “It was a good buy,” says Myles Gate, 13. He hopes to be a banker one day.
The school’s two graduating classes of 2005 and 2006 have each earned about $10,000 in profits(利润).

A popular shopping bag has been seen on the arm of some of the world’s most beautiful women. It sells at an official price of ￡5, but as much as ￡400 online. The bag called “I’m Not a Plastic Bag” is made of cotton. It is so “hot” that now everyone wants to get one. It’s fashionable, and it’s green!

Supporters see the bag as a way to move away from throwaway(一次性的) plastic bags that are given away in large numbers by supermarkets every year.

When the bags were first sold, about 500 people waited in line to buy one. So far, 20,000 of the popular bags have been sold at the second largest supermarket in Great Britain. It is one of the ways to encourage shoppers to use the reusable(可再利用的) bags, rather than the plastic ones.

The bag has also become a must-have for many famous people who want to be fashionable, and at the same time care about the environment.

The designer of the bag has been asked to develop the bag by the “We Are What We Do” group. The group believes that each person in Great Britain uses about 167 plastic bags every year. It says that small lifestyle changes can have a strong effect on reducing waste and the environmental pollution.
